1 After the casting of the raw iron pan is completed, before leaving the factory, in order to prevent serious corrosion caused by improper storage and transportation in the sales process, some rust prevention treatment is generally done. Therefore, the surface of the new wok will look shiny and feel greasy by hand, indicating that the antirust treatment agent has been sprayed, as shown in the following figure 1. These treating agents, together with pig iron in the casting pot, have a special smell and must be deodorized before cooking.

2 Deodorize first. Add 1: 1 water and cooking oil to the pot, add a handful of tea leaves and bring to a boil. It is best to use animal fat, and the amount of oil should be enough to scrub the next door. Turn off the heat after boiling, and pour the oil and water all over the wall with a spatula, and repeat it several times. After the cease-fire, when the oil and water are hot, if there are any fine sand, sawdust or chaff, add some or none to the oil and water, and then brush the whole pot wall with a brush. Then pour off the oil and water, rinse with hot water, and then proceed to the next step.

The function of tea is to remove the iron smell of iron pots. If there is no tea, you can use salt and ginger instead. First dry the new wok, sprinkle a few handfuls of salt into the wok and stir-fry until the salt turns yellow, then gather the salt at the bottom of the wok, add cooking oil and ginger, stir slowly, and then add water to boil. After the water boils, spray the pot wall several times. Then cease fire and brush while it is hot.
